This is my first try with cooking shellfish sous vide : a lobster tail.

I looked at Thomas Keller’s time and temperature table which mentioned a cooking temperature at 60°C during 15 minutes for a lobster tail. I am realizing more and more that Baldwin’s Sous Vide Guide is very practical. The information about the thickness is key. Douglas Baldwin indicates a 20 mm shellfish is pasteurized at 60.5°C at the condition being cooked during 41 minutes. I have decided to follow Douglas’ recommendations.

I took off the shell and seasoned the lobster tail with salt, pepper and a frozen teaspoon of  “extra vierge” olive oil. After cooking I seared the lobster tail some seconds in a skillet with some olive oil.

 

 

 

 

The result was very good. The flesh of the lobster was moist and had a very pleasant flavour of olive oil.

Another successful try!

I am just coming back from summer holidays and unfortunatly I’ll have to give back my Jubalo EC immersion circulator next week! Sniff!
In the meantime here is the result of my first try of cooking sous vide chicken legs.

I saw on Twitter a post from 3beanespresso who was asking himself why his try of sous vide chicken legs at 66°C for 38 minutes was leading to a gory result http://twitpic.com/fo3tl.
There was a long time that I have not looked at Douglas Baldwin “A Practical Guide to Sous Vide Cooking”. I realized 3beanespresso used Douglas table. I therfore decided to try myself 64°C during 60 minutes (on chicken leg was 30 mm thick and the other one 35 mm).

sous-vide-at-home-julabo-chicken-64c2b0c-marinade-douglas-baldwin-poultry-time-temperature-table

I found on the net a recipe for the marinade :

  • 1 tablespoon minced ginger
  • 1 minced garlic clove
  • 3 tablespoons Hoisinsauce
  • 1 tablespoon hot chili sauce
  • 1 tablespoon dark soy sauce
  • 1 tablespoon honey  
  • 1 tablespoon water

I took the chicken skin off and immersed the chicken legs 3 hours in the marinade. Then I took off most of the marinade surrounding the chicken before vacuum sealing the chicken legs. This way I have avoided leakage of marinade inside my non profesional vacuum sealer machine. I think next time I’ll freeze the marinade.

After cooking I seared the poultry some secondes with my blowtorch and a little bit of oil, just to make the chicken looking more appetizing.

sous-vide-at-home-julabo-chicken-64c2b0c-marinade-3The result was fantastic! I could realy feel the marinade and the chicken was moist and perfectly tender.

I will definitly try again this recipe and next time add 10 minutes more to the time indicated in Douglas Baldwin’s table.

Sous Vide by Thomas Keller – Precise Cooking Time and Temperature for Poultry and Meats (Under Pressure)

by on Aug.26, 2009, under Time and Accurate Temperature

under-pressure-cooking-sous-vide-thomas-kellerHere are some of Thomas Keller information about cooking times and temperature.

Contrary to Viktor Stampfer’s book that indicates a temperature of the waterbath slightly higher to the core temperature of the ingredient contained in the pouch, Thomas Keller indicates the starting temperature (3.3°C) of the food, the time and the temperature of the bath only. This is definitely less confusing.

Sous Vide : Soft boiled egg at 63°C for 1 hour

by on Aug.23, 2009, under Recipes, Time and Accurate Temperature

sous-vide-cooking-cookery-equipment-immersion-circulator-thermal-circulator-egg-63

I saw so many posts on the net speaking highly about the precise temperature and time to cook a “perfect” soft boiled egg. The range of temperature for a soft egg varies from 57°C (basically raw) to 70°C (hard-boiled, right before it gets that green ring around the yolk).

After reading the Cookingissues article about soft eggs I decided to try the 63°C soft boiled egg cooked for 1 hours with my Julabo immersion circulator. In this article they say my “ favorite 63°C “custard egg”—so named because of the creamy consistency of the yolk, which cannot be achieved with conventional cooking”.

sous-vide-cooking-cookery-equipment-immersion-circulator-thermal-circulator-egg-63-c

My 63°C soft boiled egg has not reached my expectations. The yolk was not as creamy as mentioned in the Cookingissues article. The egg was good but nothing special in my opinion. Next time I’ll raise the temperature of 1°C (64°C) and see what happens.

By the way I’ll also read carefully this fantastic article from Khymos.
